GAS-PURIFIER.

SPECIFICATION forming part of Letters Patent No. 629,739, dated July 25,1899.

Application filed December 19,1898. Serial No. 699,638. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM J. BAULIEU,

' new and useful Improvements in Gas-Purifi ers, of which the followingis a specification.

This invention relates to new and useful in] provements ingas-purifiers, and is more particularly adapted for use in connectionwith acetylene-gas machines such as are now com monly used forilluminating purposes.

In the use of acetylene-gas machines I find that the gas burners, pipes,850., will invariably clog and choke up after comparatively short usageowing to the great amount of substances which are carried from thecarbidgenerators either mechanically or otherwise. These substancesconsist principally of lime, largely of carbid, iron, and crystalformations. Anumber of devices have been incorporated in theconstruction of gasunachines for cleaning the gas; but they areall moreor less defective in that they do not properly and sufficiently purifythe gas in a manner which will thoroughly prevent the objections soughtto be overcome by this invention.

It is therefore the object of my present invention to provide a devicewhich may be attached to a gas-machine or to the service-pipe leadingtherefrom whereby the mineral substances are retarded and separated fromthe gas and the latter allowed to freely pass on to the burners.

With the above objects in view my invention resides and consists in thenovel construction and combination of parts set forth in theaccompanying drawing, forming a part of this specification, and whereina central sectional perspective view of my separator is shown ready foroperation.

Referring to the characters of reference marked upon the drawing,Aindicates a tank, which is preferably of cylindrical shape, having anouter wall B and an inner wall C, an open top, and a closed bottom D.The interior of this cylindrical tank forms a packingchamber E and isprovided with a solid bottom F and a false or perforated bottom G, thusleaving an intermediate chamber H.

I indicates an inlet-pipe which serves as a means for connecting thepurifier to the machine or to the service-pipes leading from saidmachine.

The interior of the cylinder in practice is packed with suitablepermeable material J- such as cotton, wool, or the like-which pack ingpermits of the free passage of gas therethrough, but retards andprevents the pas sage of any and all substances, either in lumps or dustform, and thereby insures the desired separation of the gas and dust.

The permeable packing material above referred to is replaced from timeto time as it becomes filled with the substances mentioned and itschamber cleaned, after which the perforated bottom can also be detachedand the intermediate chamber likewise cleaned,when the parts can againbe replaced and a new packing inserted.

The cover K is of special construction and comprises a deep exteriordepending flange L, which in practice extends down into thecylindricaltank and is partially submerged in a body of water contained therein,which water forms a seal and prevents the escape of any gas from thepurifier. Upon the under side of the cover is formed a chamber M, theside Walls of which snugly engage the inner walls of the cylinder, andthe bottom of said chamber is perforated similar to that of the bottomG. In practice this perforated bottom rests snugly upon the packing andholds it in place. An exit-pipe N extends from said chamber and servesto lead the purified gas therefrom out of the machine for use.

I It will be obvious, of course, that with an excessive pressure of gaswithin the purifier the cover will yield or raise, and thereby relievethe strain brought to bear, and, further, that with the first passage ofgas said pressure will be quickly relieved, whereupon the cover willassumeits normal position. It is also apparent that the gas enters thepipe I at the bottom and gradually works up through the perforated disksand the permeable packing material and finally emerges into the cham herM, from which it is fed to the burners through the exit-pipe N.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. In a gas-purifier of the class described, the combination with aninternal packing- IOO - a discharge-pipe, substantially as described.

2. The combination in a gas-purifier, of a cylindrical Water-tank, aninternal packingchamber, an expansible cover fitted into said Water-tankand having a central depending receiving-chamber formed integraltherewith and fitting into the packing-chamber, a detachable perforatedbottom tosaid packingchamber, an intermediate chamber and exitpipe,substantially as shown and described.

In testimony whereof I have hereunto set my hand this 10th day ofDecember, A. D. 1898.
